Changing the Drive Belt
Run the carriage to the tongue end of the mill.
Ensure machine power is off by removing the key from the engine’s ignition.
Release blade tension by venting the hydraulic pressure (see
Figure 32
on page 32).
Open the cowling doors and
remove the blade
. See
“Changing Blades”
(
page 43
) for
proper procedures and safety precautions.
Loosen the 1/2” jamb nut
(Step
1)
on the bottom side of the
tensioning device.
Loosen the 1/2” nut
(Step 2)
on
the topside of the belt-tensioning
device.
Loosen the 3/8” bolt
(Step 3)
on
the top pivot followed by the 1/2”
bolt
(Step 4)
on the bottom pivot
of the tensioning device. This
will allow the tensioning device
and belt to loosen.
The belt is now ready to be
removed. Pull the belt off the
clutch side first then the drive
wheel side.
Replace the new belt in the
opposite manner, over the drive
wheel first, then over the clutch.
In some cases you may need to
rotate the clutch housing and roll
the belt onto the clutch.
Once the belt is in place, pull the
belt tension device downward as
much as possible and then run the top 1/2” nut
(Step 2 reference)
downward
until the belt is
snug. Belt tension should be “taut” with no more than 1/2” of deflection in the belt.
Rotate the drive wheel several times to ensure the tension is spread though out the belt
and not just in one spot on the belt.
After rotating the drive wheel you will need to re-tension the belt until there is proper
tension on the belt (1/2” of deflection, see
Figure 33
on page 33 for visual illustration).
NOTE:
You may need to rotate the wheel more than once after each belt tension adjustment
to verify proper tension.
Once the proper tension is achieved, tighten the bottom 1/2” jamb nut
(Step 1 reference)
,
3/8” bolt
(Step 3 reference)
on the top pivot and 1/2” bolt
(Step 4 reference)
on bottom pivot.
Replace the blade and re-set for proper blade tension. Remember to also verify proper
blade tracking, guide alignment and blade lead.
Once the above items have been completed, close the cowling doors.
